Crassula columnaris many white flowers

A prodigious head of white flowers, this Crassula columnaris plant is going out with a bang. Whatever is done once in a lifetime only, better be done with all that can be mustered.

The longish corolla tubes include their stamens and styles. The five oblong lobes at each tube tip spread but not in a very regular way, somewhat two-lipped but variably so. Corolla diameter is about 5 mm.

The flowers not yet open are scattered in the inflorescence, not in the centre as would be the case in a daisy disc or in a ring on the outside (Vlok and Schutte-Vlok, 2015; iNaturalist).
